Abstract: In a motorcycle tire, since a reinforcement cord that constitutes a belt layer (24) is constituted by a cord having a low modulus of elasticity (a tensile force upon 1% elongation is 15 N or less), a shearing force in a circumferential direction of a tread (26) is decreased. As a result, a value of frictional energy is decreased, and abrasion resistance of the tread (26) (a center section (27)) is improved. Moreover, since tan ? of shoulder sections (28) is larger than tan ? of the center section (27), a grip limit in the shoulder sections (28) that are grounded upon turning is increased, and turning performance is improved.

Abstract: In measuring a dissolved substance, a concentration of a specific dissolved substance in a sample water is measured using a measuring water W1 developing a specific color within a specific pH range by adding each of two reagents to a sample water W0, and an acid-base indicator S developing different colors other than the specific color is selected in a first pH range including the specific pH range and a second pH range deviating from the first pH range. Next, a reagent is prepared by adding the acid-base indicator to one reagent wherein a pH value of a reagent added water where the two kinds of reagents are separately added to the sample water is within the second pH range. Next, absorbance values are calculated by three region component lights which are a transmitted light in the measuring water wherein the prepared reagent is added.

Abstract: A reagent includes a coloring agent allowing a measured solution to develop a color transmitting a region component light for a dissolved-substance concentration measurement selected from three region component lights of red, green, and blue obtained by transmitting a light including a visible light region to the measured solution colored by addition of the reagent to the sample, and dividing a light of the visible light region of a transmitted light thereof into roughly three portions. Based on the transmitted light from the measured solution with the coloring agent added, an absorbance of the region component light for the dissolved-substance concentration measurement, and an absorbance A3 of another region component light resulted only from the coloring agent are calculated. Whether or not the reagent in a necessary quantity is added to the sample can be judged by comparing the absorbance A3 and a standard absorbance A0.
